The more we think about this one the more we like it. [Michael] built himself a wind-powered persistence-of-vision weather station. Okay, that sounds interesting, but he ups the ante when you find out what’s included in the system. A stepper motor acts as the generator which powers the electronics. As we’ve seen before; if you spin [...]

This hard-drive based POV clock is a treasure trove of great design choices. Now, we’ve seen a bunch of spinning clock builds. Several of the hard drive versions use slits cut in the platters to create a display by illuminating an LED behind those slits at just the right moment. This is a similar idea but [...]

Confronted with the issue of finding a use for his mounting pile of junk electronics, [Rue] set out to build a persistence of vision device using a hardware state machine. We have a suspicion that his original link may go down if there’s too much traffic so here’s a cached link just in case. Any [...]

[Ryan]‘s cylinder POV display is an amazing piece of work. Right now it’s impressive sitting on his workbench, but we’re sure it would be astonishing hanging above the middle of a dance floor. There are 64 RGB LEDs on this display and they’re certainly bright enough to liven up any space. Power is provided through a slip [...]

[Ch00f] spent some serious time figuring out how the Icebreaker POV toy works. This is a pretty cool device about the size of a toothbrush holder. It’s in a clear plastic case, which lets the row of 32 surface mount LEDs shine through. But making light isn’t their only function. You can use the device [...]

So we saw this tip come in and thought–oh, another POV device. We watched the video (embedded after the break), took a sip of coffee, then almost sprayed the beverage all over the computer when we realized that this uses a diy sensor to synchronize the POV image. [Ch00f] came up with the idea for [...]

You too can paint your favorite meme in light with just a few tools. [Skywodd] brought together a couple of different projects to make this happen. He had already built a large POV display and now uses a DSLR with long exposure to create light paintings (translated). The Arduino-powered display is built from a strip [...]

We’re no strangers to POV time pieces around here, but something about them never gets old. Whether they use a ring of LEDs to draw clock hands, or an intricately cut HDD platter to replicate LCD segments, we love seeing them. [David] sent in this hard drive POV clock built by a fellow named [Kly], [...]

[Augusto] wrote in to tell us about his keychain-sized persistence of vision project. He built the original prototype on some protoboard, using a PIC 16F627 to drive eight LEDs. Synchronization is managed by a tilt sensor on the board that starts the strobing to match the direction the board is traveling. This is a similar [...]

[Zach's] company is all about the safety and to reinforce those ideals they handed out POV display fans to each employee. “Being Safe is Cool”, get it? Gimmicky… yes, but now [Zach's] got a tiny little POV fan to hack. Although he may not have known it, this isn’t the first time we’ve seen this hardware. These fans were [...]

A user named [BOcnc] on the rcgroups forums just posted his RGB POV helicopter blades. The two blades are attached to the heli just as any other whirlygig. The electronics, though, are mounted underneath the blade with a battery pack. We covered a build last year that demonstrated weight added to a spinning blade won’t [...]

Last year, when [Alex] was asked by his friend [Martin] to help him out with building some LED POV modules for a race car, his response was a enthusiastic “YES!” [Martin’s] goal was to involve fans more deeply in the race, so he decided that the POV modules would carry messages from fans on-board, printing [...]

Hackaday reader [svofski] sent in a fantastic looking hard drive-based POV clock (Google Translation) created by a maker in the Sichuan province of China. The clock, like the one [svofski] built, relies on LEDs placed behind the spinning platter to create the POV effect. Quite a few carefully placed cuts have been made to the platter, [...]

It’s a holiday weekend, and much like you, we’re taking a bit of time to relax and kick back a few drinks while we mingle with friends and family. Obviously, one of the bigger events this weekend plays host to is the fireworks show put on by your city or your drunken neighbors. Roman candle [...]

When you really want your feelings known, we always say that bigger is better. [Gavin Smith, aka The Mechatronics Guy] must come from the same school of thought, because there’s absolutely no mistaking what he is trying to say with his latest project. Inspired by this WiFi signal painter we featured a while back, the [...]

We see lots of persistence of vision projects around here, but we can’t recall any that involve a POV display facilitated by a living, breathing animal (humans aside, if you want to picky). [Michael] has a Miniature Pinscher that just loves to run and run…and run…in circles. Since she generally runs very fast and in [...]

We’ve already added the components needed to build [Rucalgary's] tiny POV device to our next parts order. The little device sets a new standard for tiny persistence of vision boards. Instead of relying on the user to find the best speed and timing for swinging the board around, [Rucalgary] used an accelerometer. This is the [...]

We love spinning POV displays but have yet to build one to call our very own. This project might be the one that we end up building. It’s looks good and it’s the only persistence of vision display that comes to mind which can be built in twelve hours. The spinning is taken care of [...]

Some say that handing out business cards is an antiquated practice due to the ubiquity of smart phones which can be used to trade or record contact information in mere moments. Instructables user [sponges] however, doesn’t agree and is pushing a “business card renaissance” of sorts with his POV business card. Hand-built in his basement, [...]

[Retrobrad's] spinning POV display has long been our favorite. When it popped up on our radar again this morning we were surprise to see we never ran a feature on it! But now there’s so much more to share. Hit the projects icon at the top of his page and you’ll not only get the [...]

Yes! A radio control helicopter with a fairly high-resolution persistence-of-vision display is a beautiful thing. [Mziwisky's] handiwork is the result of several steps along the prototyping path. He built up a POV test rig on a breadboard, designed his first PCB for the project, and then went to work building it. After initially being inspired by [...]

[Kizo] built an extraordinary persistence of vision clock. The design uses a PC cooling fan to spin the propeller-like PCB. As it goes around, a hall effect sensor synchronizes the illumination of the LEDs to draw the display. Power for the rotating electronics is transferred wirelessly via a transformer on the base and coil on the [...]

[Ytai] let us know about his POV globe, all four parts of its current progress. While he says he was inspired to write up the project from a YouTube clip, we know the real reason. Regardless, the plan is to have a 2 foot diameter globe with 256 LEDs spinning at 50 revolutions per second [...]

We put a temporary ban on posting POV projects after receiving several LED spheres back in May. But we had to lift the injunction after seeing this superb Volumetric 3D POV display by [Wes Faler] and [Don Smith]. Their creative use of several readily available components adds to the alluring setup; the central elements being [...]

Here’s a slick version of a POV globe(google translated). Created by [Riko], this globe has 32 LEDs and is powered by a rotating coil. The layout looks fairly solid in operation, with the POV effect showing up very nicely on camera.  You can get the schematics and source code from the project page. We found [...]

This gorgeous persistence of vision clock was built a couple years back by [mb1988]. The housing is made of acrylic with a hard drive motor mounted in the center of the back panel to spin a PCB. The two-sided circuit board is home-made and includes a battery for power, ATmega32 for the brain, 32 LEDs, [...]

Strobeshnik is a somewhat different twist on the hard drive clocks we’ve seen in the past. Though still technically using a POV effect, the Strobeshnik displays the numerals instead of a line. By altering strobe timing of an LED behind a platter with the numbers cut into it, he can display whichever number he wants. [...]
